To all whom it may concern Be it known that 1, Louis C. KRUMMEL,

a citizen of the United States, residing at Clinton, in the county of Middlesex, State of Connecticut, have invented certain new and useful Improvements in Can-Closing Machines, of which the following is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.

The invention relates to new and useful improvements in machines for placing an end or cover on a can, and more especially to machines for double-seaming a cover on a filled can.

An object of the invention is to provide a machine of the above character wherein the filled cans may be placed on a continuously moving carrier or turret and the cover or end secured to the filled can during the travel of the carrier or turret.

A further object of the invention is to provide means for receiving a cover and for seating the cover on the filled can during the travel of the carrier or turret.

A further object of the invention is to provide a rotating carrier or turret which is provided with a plurality of seaming stations, each of which may be operated to secure a cover or can end to a filled can body during the travel of the carrier or turret.

A further object of the invention is to provide means in a can-closing machine of the above character, which strips the filled can from the seaming mechanism, and which discharges the filled can from the rotating carrier or turret.

A still further object of the invention is to provide a machine of the above character with automatic means for feeding one cover at a time to each seaming station, and for positioning the same over. the holder or support forthe filled can.

' the seaming heads, showing in plan the feed- These and other objects .will in part be.

Prior to my invention, I am aware that can-closing machines have been constructed wherein a filled can may have, the cover double-seamed thereon.

The present invention consists primarily in providing a closing machinehavmg a plurality of'sea'ming Stations which are moved :of the same; and Fig. 20 is a verticat 'sec-- I the parts f continuously past a feeding-in point where the filled cans are delivered to the rotating carrier supporting the seaming stations, after which the cover which has also been fed to the rotatingcarrier is seated in the can body during the travel of the carrier, which can cover is secured to the can body by a double-seaming joint also formed dur' ing the travel of the carrier.

In the present embodiment of the invention, the filled cans are delivered on toa can support which is raised to bring the filled can body into seating contact with the cover, and during this movement of the filled can body the can is rounded up and centered relative to the cover. After the cover is seated the can body, the can with the cover thereon is raised against a rotating chuck, which causes the can to be rotated. During the continued travel of the carrier, the rotating can is positioned so that seaming rolls are brought into contact with the flange of the cover and the can body, and the parts rolled into a double seam. After the closing of the cover, and during the continued rotation of the carrier, the seating pad for the cover strips the can from the chuck,

which is lowered with the support therefor and is finally swept from the closing machine by a suitable stripping arm.

Referring more in detail to the drawings, my improved can-closing machine consists of a supporting base 1 from which rises a standard 2 having an overhanging arm 3. The overhanging arm 3 is formed with a bearing sleeve 4, in which rotates an axle or center shaft 5, carrying an upper turret 6 and a lower turret 7. The axle or shaft 5 is mounted at its lower end in a suitable bearing 8.

The lower turret 7 I supports a table 9,

' which is formed with suitable openings 10,

in which are located can supports 11. Each of the can supports 11 is carried by a stem 12, which is mounted to rotate in a supporting sleeve 13, see Figs. 7 and 13. The lower end of the stem 12 rests on a hardened hearing 14, which is carried by an adjustable screw 15. 1

The sleeve 13 supportingthe stud 12 is recessed as at 16, and the lower-end of 'thescrew 15 is formed with a squared head 17, extending into the recess 16. By-jtur'ning the screw 15 the support'll may be' adjusted vertically relative to thesupporting sleeve 13 therefor. means for locking ,the adjustable screw in various vertical positions. The sleeve 13 is provided with a laterally projecting-pin at its lower end, on which is mounted a roller 19. .This roller is adapted to coiiperate with a cam groove 20 formed in the cam disk 21.

'The cam disk 21 is loosely mounted on a sleeve carrying the lower turret 7, and is held from rotation by a rod 22, which pro- Aset screw 18 serves as anut 23 is threaded on the axle or shaft 5,

and by adjusting the nut 23 vertically, the, turret 7, together with the supporting table 9 and also the operating cam disk 21 may be raised and lowered. The purpose of this vertical adjustment of the lower turret is to adapt the machine for operation upon different sized can bodies, as will more fully appear hereinafter.

The can support 11 is slightly larger than the can which is to be closed, and this support is adapted to rotate with the can after the can is in engagement with the rotatmg chuck. To aid in positioning the can bodies directly underneath the seaming heads and centrally on the supports 11 therefor, I have provided the table adjacent each support with a centering guide 24, see Figs. 7 and 13. These centering guides are formed with raised portions 25, 25, which are adapted to engage the cylindrical part of the can body and position the same directly over the support therefor. Each support 24 is carried bya rod 26, which slides in a bearing 27 formed on the lower-turret. The sleeve 13 which serves as a means for supporting the can support, also slides vertically in the turret 7. An arm 28 is secured to the sleeve 13 for the can support, and this arm is rigidly attached to the'rod 26 carrying'the can-centering guide, so that when the sleeve for the can support is raised and lowered in the turret, through the action of the roll 19 in the cam groove 20, the can guide will also be raised and lowered with the support and the rod 26 will slide in the bearing 27 to permit this movement.

The filled can bodies are fed to the lower rotating turret by a drum feed, which consists of a rotating drum 29, mounted upon a horizontal axis. The drum 29 is journaled in a table 30, which is carried by standards 31. The upper surface of the table is smooth, and is provided with a slot 32,

through which extends the thread 33 formed on the drum. The filled cans are placed on the upper surface'of the table and against a guiding rail 34. The thread on the drum engages the cans, and as the drum rotates, said cans will be gradually carried toward the rotating table mounted on the lower turret. This supporting table 30 for the filled can 1s, of course, stationary, and the seaming stations of the rotating turret pass one after the other past the end of the supporting table. v

p The guide rail 34 extends over the table 9, as clearly shown in Fig. 7. The thread wound on the drum is of continuous pitch,

except .at the end thereof, where the thread extends substantially transverse of the axis of the drum, as shown at 35, Fig. 3. The can is forced from the supporting table on to the table 9, and then on to the can support 11, through the action of the thread on the drum and through the cooperation of the filled cans themselves. In other words, the filled can 36, as shown in Fig. 3, in arriving at the position shown therein, crowds the next can in advance thereof forward along the guiding rail 34 on. to the can support 11, and against the can-centering guide 24. This can 36, however, will remain in this position until the next seaming station approaches, when the next adjacent can 37 on the drum will be brought forward and force the can 36 into the next seaming station.

- In order to assist in placing the cans on thecan supports 11, I have provided a yield ing guidingfinger 38, which is pivoted at 39, to the supporting table 30. This finger is held pressed at its outer end against a stop pm by a spring 41. The filled can, as clearly shown in Fig. 7, passes between the guiding finger 3S and the guide rail 34, and is forced on to the can support 11. The continued rotation of the lower turret 7 and the table 9, will cause the finger 38 to yield and allow the can to pass the same. This passing of the can by the finger 38 will, however, properly seat the can against the centering guide 24.

Asa further means'to assist in the proper positioning of the can body on the support 11 therefor, I have provided a curved finger 42,'which is attached to the supporting rail 34. This curved finger 42 is clamped by a bolt or other suitable means to the rail 34 so that said finger may be adjusted about its clamplng bolt for changing the angular posltion of the finger relative to the rail. This curved finger engages the. can body adjacent the center thereof and prevents'any possible chance -of the filled can being tipped over the centering guide 24 therefor.

u The drum 29 is rotated in proper-timing w th the rotation of the central axle or shaft 5, through a gear and sprocket connection, which, as herein shown, consists of a bevel gear 43,mounted on the lower end of the axle 5, and meshing with a bevel gear 44 on a cross shaft carried in a suitable bearing formed on the supporting base of the closing machine.

The outer end of the cross shaft is prov1ded with a gear 45,-which meshes with a gear 46, mounted in a bearing carried by the arm 47.

cross shaft. This bearingfor the cross shaft is'split, and is provided with a screw 48 by which the sleeve for the arm 47'is clamped in various angular positions relative to the cross shaft. A. sprocket chain 49 engages The arm 47 is rigid with a sleeve extending into the bearing for the the gear 46, and also a sprocket wheel 50 carried on the inner end of the drum 29.

The standards 31 may be adjusted vertically by a hand wheel 51. Thesestandards are adjusted by threaded nuts which are.

simultaneously actuated through a connect.-

ing sprocket-chain 52. Throughthe aid of this mechanism, the drum may be adjusted vertically and simultaneously at both ends thereof.

may be quickly made, I have provided the shaft 53 which supports the drum, with a series of holes 54. A collar 55 is adapted to be adjusted on the shaft 53, and a pin slipped through the collar and one of the holes 54. This collar is held from longitudinal movement relative to the supporting bearing for the drum in any suitable way as by a thread ed screw carried by the support projecting into an annular groove in the collar, and when the collar, or rather the shaft is adjusted in the collar, the drum is moved endwise.

The holes for the pin are so positioned as to properly locate the drum for different sized cans within certain ranges. This adjustment provides for an exact positioning of the drum, and a relatively quick adjustment of thedrum, so as to adapt it for feedin .in cans of different sizes.

e coversfor the filled cans are stacked in a holder 56, which, as herein shown, con sists of three equally spaced rods 57 These rods are carried by a bracket arm 58, which is secured to the standard 2, and projects laterally therefrom. Said bracket arm car- 'ries a cover support 59. see Figs. 3 and 4.

porting screws 63, 64 and 65. These screws.

are threaded so as to support the stack, and as the screws turn, release at proper intervals the lowermost cover in the stack.

The screws which support the covers are driven in unison by a sprocket chain .66. which runs over an idler 67, whereby'the .slack in the sprocket .chain may be properly takenup. The screw 65 is mounted When the drum is adjusted, the" arm 47 may be swung about the center of on the lower end of a vertical shaft' 68, which is operated in proper timed relation to the rotation of the carrier by devices which will be hereinafter described.

At each seaming station is a cover holder 69, which is supported by the upper turret 6. This cover holder is formed with a central tapered opening 70 and a supporting ledge 71 for the cover. The opening at the upper end of the tapered portion is slightly smaller than the cover before said cover is placed and double-seamed on to the can, so

i that the cover may be fed on to the supporting ledge 71 and rest thereon. This cover holder is located directly above the can body support 11, and when the filled can is positioned on the can support, said filled can is directly underneath the cover holder, so that when the support 11 is raised through the action of the cam 20 on the roller 19, the upper end of the can body will be carried up through the tapered opening 70 into engagement with the cover in the holder. It may be noted in this connection that this tapered opening formed in the cover holder will serve to round up the can body if it is out of true, and also serve to center the can body so that it will properly engage the cover.

' The covers are delivered from the stack on to the supporting ledges 61 and 62, as

above noted. The cover holder is provided with a laterally projecting ledge 72, and with an upwardly projecting lug 73. This lug passes underneath the cover support 59,

entering a slot 74 formed through or at the end of the supporting ledge 61. The cover,

-therefore, resting on the ledge 61 and the ledge 62 will be picked up by the lug 73 and carried forward as the turret rotates. The inner edge of the cover will be transferred from the ledge 62 on to the projecting ledge 72 of the cover holder. The outer ledge 61 or the surface of the holder directly above the same, is formed eccentric to the axis of rotation of the turret, and is so disposed as to gradually crowd the cover over the surface of the holder 72 and on to the supporting ledge 71. The ledge 61 at the-delivery end thereof is also grooved or cut away, as indicated in dotted lines, to allow the lug 73 to pass therethrough.

Each holder is provided with a fixed or rigid covenguiding bar 75, and a pivoted guiding bar 76, which is yieldingly pressed toward the fixed bar 75. These guiding .bars are formed with overhanging parts, underneath which the cover passes to the seating or supporting ledge 71. The purpose of the yielding guiding bar is to grip the coverwith suflicient force to prevent the same being displaced. A stop 77 is also mounted on each holder, to assist in positioning the cover on the supporting ledge 71. As the cover passes by the end 78 of the cover support, it will be properly posiapparent that I have provided an automatic cover feed wherein a single cover at a time is delivered to and properly positioned in a holder carried by a continuously rotating turret, and that each seaming station as it passes the cover feeding-in point, may be supplied with a cover.

After the cover has been placed in the cover holder and a filled can body positioned underneath the same, a seating pad 79 moves into contact with the cover. The filled can is then raised into contact with the cover and the cover lifted with the seating pad, so as to bring the seated cover of the can body into engagement with a chuck 80. The rotating chuck 80 and seating pad 79 are carried by the upper rotating turret 6; This upper turret, as shown in Figs. 9

and 10, consists of a central sleeve 81, which ings 86 and 87.

. The rotating chuck is mounted in the central sleeve 85, and is held against endwise" movement therein by suitable adjustable locking collars 88 and 89. A gear 90 is secured to the upper end of the chuck sleeve, and the gear of each chuck meshes with a common gear 91, carried by a sleeve journaled in the overhanging arm 3. This sleeve at the upper end is provided with a belt pulley 92, which is driven by a belt 93 from the main shaft 94. The belt 93 runs over suitable idlers, so that the horizontally arranged driving pulley may operate the vertically arranged pulley 92.

The seating pad 79 1s carried by a rod 95, and the sleeve for the chuck 80 is mounted to rotate about said rod. This rod at its upper end carries a bracket 96, which is formed with laterally projecting arms 97, and which carries a roller 98. The roller 98 engages a cam groove 99, in the cam 'disk 100, which is freely mounted on the supporting sleeve carrying the ear 91. The cam disk 100 is held from rotating by a bolt 101, which engages the overhangin arm 3,

see Fig. 2. The arms 97 projecting aterally from the bracket 96 engage'the side face of the cam disk100, and prevent the rod 95 to the cam groove 20 in the cam disk 21, as to properly coiiperate with the same in the seating of the cover,'and in the raisin of the can body with the cover seated, into contact with the rotating chuck.

After the cover is placed on the cover holder, as the carrier rotates, the rod 95 will be lowered, so as to bring the seating pad 79 into contact with the cover. The cam groove 20 then. raises the filled can u against the cover, and the can body is crowded on to the cover, so that the cover is seated therein. After'the cover is seated in the can body, the rod 95 is raised with the further lifting of the sleeve of the support for the can body, and the filled can with the seated cover thereon is carried up into contact with the rotating chuck 80. The seat ing pad 79 is held from rotation, and, therefore, the can body with the cover thereon will not rotate until the cover is firmly seated in the can body, and held seated therein through the clamping action of the seating pad and the support 11 for the can body.

As soon as the cover engages the chuck, the seating pad is relieved therefrom sufficiently to allow the chuck to rotate the filled can with the cover thereon, and the support 11 for the can body rotates in the sleeve 13 which allows the can to rotate freely.-

As above noted, the cover-holder 69 is carried by the turret 6. Adjacent each end of the cover-holder is a rod 102. These rods 102 are adjustably secured in the bearings 87 carried by the laterally projecting parts of the bracket 84. By supporting the cover-holder at each end thereof, said holder will be firmly held in proper position relative to the rotating parts of the seaming station, and, therefore, will properly position the cover, and may be utilized for rounding up and centering the can body relative to the cover. Upon a further travel of the carrier, the can which is clamped to and rotated by the rotating chuck, is operated upon by the seaming rolls, whereby the fiangeof the cover and the can body are rolled into a double seam. The seaming rolls consist of a first and second operation roll 103 and 104: respectively. The means for supporting the seaming rolls are essentially the same, and the description of one will serve for the other.

Fastened in the bearings 86 is a short stud 105, which projects below the sleeve 85, see Fig. 1. This stud carries a seaming lever having an arm 106, which carries the seaming roll at its lower end. The lever is also formed with-a lug 107, in which is mounted astud 108 carrying a roller 109, adapted to cooperate with a cam 110.

lt'will be understood that there are two cams 110, one ofwhich operates the first seaming roll and the other of which operates theother seaming roll. These cams therewith.

iii

are clearly shown in Fig. 8. The cams are mounted loosely on the central axle or shaft 5, and are held from rotation by an arm 111, which'is secured to the standard 2. These cams are so positioned and constructed as substantially a directly applied force. The

position of. the seaming roll relative to its operating cam may be readily adjusted by adjusting the position of the stem 108, which carries the roll cooperating with the cam. This may be accomplished by inserting blocks or washers 112 of the proper thickness on the stems between the shoulder of the stem and the arm 'on which the stem is mounted.

In order that the final closing or secondoperation roll may be yieldingly forced into contact with the seam, and thusallow for any ine uali'ties such as side seams, I may use a yie ding washer 113 in connection with the second operation roll.

The central axle carrying the turrets is rotated through a gear connection with the driiiing pulley 92, connected with gear 91. Said driving pulley 92 has a gear 114 fixed thereto. This gear meshes with a-gear 115 carried by a countershaft 116. A gear 117 is attached to the gear 115 so as to rotate This gear 11 meshes'with a gear 118 on a second countershaft 119. The gear 118 in turn meshes with a gear 120, which is keyed to the central axle 5. By this construction, I have .provided a reducing gear mechanism, so that the rotating carrier consisting of the upper and lower turrets may be caused to travel 'at a muchslower speed than the rotating gear 91, which operates the rotating chucks. shaft 119 also carries a sprocket wheel at its upper end and a sprocket chain 121 conveys the movement of this countershaft 119 to the vertical shaft 68. It will, therefore, be seen that the vertical shaft 68 Wh1ch feeds The counter-' the can covers one at a time on to the cover support, is operated in timed relation with the rotation of the carrier.

In the, operation of my device, the covers are stacked in the stackholder, and the filled cans are placed on the supporting table 30.

' the cans.

thereon by the can-centering guide 24.

A further rotation of the carrier causes the centering pad 79 to descend on to the cover on the cover holder, and also causes the support 11 for the filled can to rise, carrying with it the filled can. The tapered opening in the cover holder, rounds up and centers the can body, so that it is brought up into contact with and seated on the cover. A further movement of the carrier causes the filled can with the seated cover to pass up through the cover holder, and to be engaged by the rotating chuck. The chuck at once rotates the filled can with the cover thereon, rotating with it the support 11 therefor.

As the carrier continues to travel, first one seaming roll and then the other is brought which the seaming rolls are caused to release The continued travel of the carrier causes the support 11 to drop, and the seating pad 79 to move down, positively forcing the filled can from the rotating chuck. The can ceases its rotation, and is carried along with the travel of the carrier on the support 11.

The guiding rail 34: projects over the table, as abo e noted, and is formed with a curved surface which engages the filled can, strips the same from the support 11 and the table 9, and forces the filled cans on to the stationary table 30 at the opposite side of the rail 34. Each seaming station as it passes the cover feeding-in mechanism is supplied in turn with a cover, and as it passes the feeding-in point of the filled cans is supplied with a filled can.

It will be seen that I have provided a continuously operating closing machine wherein the 'filled cans and the cover are presented one after the other to the rotating carrier, without in any way retarding or stopping the movement of the rotating carrier, and

after the cans have been closed they are.

stripped or removed from the rotating carrier. It will also be'noted that I have provided .a construction wherein the rotation of the carrier is utilized for seating the cover in the filled can, and also for bringing the may be readily accomplished by varyin the position of the drum in the manner a ove described, raising of the table to bring the supports for the cans into different positions relative to the seaming stations the adjusting of the seaming rollers by the. adding or taking out of the blocks on the studs which carry the rolls engaging the operating cams, and changing of the holder for the covers. With these changes, the machine may be adjusted for various sized cans within certain limits. I

While I have described my machine as especially adapted for closing a filled can, it will be obvious from certain aspects of the invention that the machine is capable of securing a can end on to a can body in the manufacture of the can. When so used, the can bodies would be received by the support and the ends-of the can placed in the holder for the cover. This holder would center the end while it would also round up the can body for the seating of the end in the can body. This seating of the can end occurs before the end and body are clamped to be rotated by the chuck.

It is obvious that minor changes in the details of construction and arrangement of parts may be'made, without departing from the spirit of the invention, as set forth in the appended claims.

Having thus described my invention, What I claim as new and desire to secure by'Letters Patent, is
